全电推进GEO卫星离子与霍尔电推进系统效能对比分析

Benefit Comparison of Ion and Hall Propulsion Systems for All-electric GEO Satellite

提出了一种全电推进GEO卫星工程通用的优选离子或霍尔电推进的对比分析方法:利用离子和霍尔电推进单机的质量模型,建立了离子和霍尔电推进系统的全质量模型;针对包括和不包括一次电源情况,应用系统全质量模型分别进行了全电推进GEO卫星轨道转移任务和全寿命(轨道转移和全位置保持)任务中两种电推进质量效益的对比分析,得到了卫星发射质量在1000~3000 kg范围内具有工程参考价值的结果。

The choice between ion and Hall propulsion systems is important for engineering implementation.A comparative method is presented to help determine which system is more beneficial.Based on the weight models for each unit of the propulsion systems,the wet weight models for ion and Hall propulsion systems are built.For both the cases that the wet weight includes and excludes the primary power,the benefits of these two types of propulsion are compared for orbit transfer and the entire mission,respectively.The results for the satellite with a launch weight of 1000 to 3000kg are obtained for reference.
